Tower knobs
 

To make a long story short I had to take my tower down for the first time and apparently the previous owner never took it down either so I snapped one of the knobs trying to get it out. Anybody know of a good place to find replacements? It's not a factory tower. The guy I bought the boat from said it was custom made years ago but I don't think the place that built it is around anymore.

Try an Orchard supply or True Value....maybe you can get a bolt to use in the mean time?

Yeah I was thinking the same as far as a bolt. That might be my best and possibly only option.

I would check McMaster-Carr (mcmaster.com). It may also help to post a photo so we can see the part.
